what does it mean about 'Button connected to pin 3 and GND.'

hi, I am doing the emoji_button.ino project. I am confused about the 'Button connected to pin 3 and GND.'

Do I need to insert my Nano 33 BLE Sense board into the TinyShield? or use a jumper to connect Pin3 and GND? I am not sure. I will appreciate it if you could relpy.

從 emoji_button.ino 專案以及說明按鈕連接到 pin 3 和 GND 的指示開始。檢查專案的硬體設定文件以及對 board 或 TinyShield 的參照，以確定預期的接線方式。完成的標準是：說明清楚解釋所需的 board 連接，以及是否需要 jumper 或 shield。
